01 Products with SMI interface<\/strong><\/h3>\n\n\n\n
<\/div>\n\n\n\n

Is the power supply for an SMI LoVo drive defined uniformly?<\/h3>\n\n\n\n

No. As a rule, SMI LoVo drives are supplied with 24 V DC. However, other voltages are also possible. The supply voltage of the drive and the power supply unit must be matched to each other. <\/p>\n\n\n\n

\n\n\n\n

What must be considered when replacing an SMI drive with another brand?<\/h3>\n\n\n\n

SMI drives from different brands are compatible in terms of the interface. This means that the specified standard commands are executed in the same way on all drives and that the addressing procedures are identical.When changing a brand or manufacturer, please note that functions, properties, and technical data of drives may differ. This includes, for example:\u2013 maximum speed\u2013 with or without creep speed\u2013 with or without speed control\u2013 adjustment procedures for end positions\u2013 installation dimensions\u2013 manufacturer-specific functions\u2013 etc. <\/p>\n\n\n\n

\n\n\n\n

How long is an SMI certificate valid?<\/h3>\n\n\n\n

A product can be considered certified as long as it is registered on the website at https:\/\/standard-motor-interface.com\/produkte\/. A certificate has been issued for these products. Products that are not registered may not be placed on the market with the SMI mark. <\/p>\n\n\n\n

If changes are made to a product or the requirements change, it may be necessary to repeat the certification process.<\/p>\n\n\n\n

\n\n\n\n

Where are SMI products registered?<\/h3>\n\n\n\n

All certified products are registered on the website https:\/\/standard-motor-interface.com\/produkte\/. A data sheet can be downloaded for each product. <\/p>\n\n\n\n

\n\n\n\n

What is an SMI certificate?<\/h3>\n\n\n\n

For products that have passed a testing and certification process, the office issues a certificate. The certificate number is listed for each product in the standardized data sheet. The certificate contains information on test reports and revision numbers of the specifications used. <\/p>\n\n\n\n

\n\n\n\n

How can I identify certified products with an SMI interface?<\/h3>\n\n\n\n

Certified products bear the SMI or SMI LoVo mark. In addition, certified products are registered on the website www.Standard-Motor-Interface.com. <\/p>\n\n\n\n
